Answer: -4/5, in decimal form -0.8
Step-by-step explanation: −4.1+2n+1+0.3n
Combine Like Terms:
=−4.1+2n+1+0.3n
=(2n+0.3n)+(−4.1+1)
=2.3n+−3.1
=2.3n−3.1
Answer:
-75.9
Step-by-step explanation:
Answer:
25
Step-by-step explanation:
b=4x+1 h=x+1 A=175
A=bh
Substitute: 175=(4x+1)(x+1)
Expand: 175=4x^2+5x+1
Subtract 175
4x^2+5x-174=0
Solve w/quadratic formula
(-5 <u>+</u> sqrt(25+2784))/8
Simplify: x=6 or -29/4
Distance is positive, so x=6
4x+1=4*6+1=25
Answer:
16
Step-by-step explanation:
The angle shown there is an example of a vertical angle. An opposite angle formed by intercecting lines. They are always congruent, so to solve this, you must set them equal to eachother. you can gather the equation 4x-5=59. From there, you just solve it like you would any two step equation.
